• This heartwarming song celebrates the spirit of a traditional holiday. The title track of Pentatonix's second holiday release following their 2012 EP PTXmas, it is the one original tune on the collection. Katy Lou Clark and Penny Lea Clark of the bluegrass trio Purple Hulls penned the cut.
• Pentatonix's Kevin Olusola told Billboard magazine why they recorded an original song for the album. "We just wanted a song that focuses on the nostalgia of Christmas," he said. "For us, we are gone so much on the road. The only time we get to spend with family is during Christmas. So we wanted to write a song that kind of focuses on that."
  
  "We're just so happy how it turned out -- it's a simple song that people can truly gravitate to," Olusola continued. "Musically it's kind of complex, but the simplicity and the musicality is what makes the song come to life."
